DAT (Digital Activation Transmission)
This automatic activation system is an exciting innovation in underwater communication exclusively from OCEAN REEF. The DAT™ system allows the option of transmitting in a hands-free mode rather than manual mode. Keep pressed the blue lever for 2 seconds to enter the program Mode. Press once the blue lever and hear DAT OFF. Press the yellow button to activate DAT MODE. Press the blue lever to exit program mode. The unit is now set in automatic transmission/ receiving cycle. To exit DAT MODE simply press the yellow button. A series of impulses are sent out, automatically keeping the unit in transmit mode for 30 seconds. After the initial 30 seconds of transmit mode, the unit will return to receive mode for 20 seconds accompanied by a series of impulses in a different tone from the first. DAT™ is useful when it is necessary to have both hands free while transmitting, making diving more comfortable and safe. Another benefit of the DAT™ system comes in the case of an emergency; by activating the DAT™ a series of impulses will emit every 30-20-30 seconds, which can be received at a great distance by search and rescue workers and other divers.
